Factoring Perfect Square Trinomials

This lesson teaches how to factor perfect square trinomials using a shortcut formula. It explains the two forms of perfect square trinomials and provides a step-by-step guide to factor them. Two examples are given to illustrate the process, verifying the factored form by multiplying it out. The lesson concludes with a summary of the key points.

What is the form of a perfect square trinomial with a positive middle term?

• a^2 - ab + b^2

• a^2 + ab + b^2

• a^2 - 2ab + b^2

• a^2 + 2ab + b^2
